Cl. 33-50 5 Claims ABSTRACT F THE DISCLOSURE .An auxiliary gun sight for use in conjunction with conventional telescopic sights. The sight includes front and rear open sighting assemblies which can be mounted on the tube of the conventional telescopic sight to enable the user to alternatively utilize the scope or the open sights. The front sight is adjustable transversely while the rear sight is adjustable vertically to permit proper registry of the weapon.

BACKGROUND OF THE INVENTION This invention relates, in general, to sighting devices for rifles, shot guns and the like and has particular pertinence to an auxiliary open sight intended to be used in conjunction with a conventional telescopic sight.

DESCRIPTION OF THE PRIOR ART The only pertinent prior art patent known to applicant is Marple U.S. Pat. 2,054,090 which does disclose an open sight which can be mounted on a telescopic sight but which lacks the adjustability and simplicity of applicants device.

SUMMARY OF THE INVENTION It is commonly known that telescopic sights can be mounted on the barrel of a conventional rifle, shot gun or similar weapon and these telescopic sights are normally placed in position on the top of the barrel in overlying relationship with the existing open sights.

Telescopic sights are, of course, of great advantage due to their magnification properties and in many instances the aforementioned arrangement is satisfactory.

However, telescopic sights are subject to certain inherent defects from time to time during operation. The primary diiiiculty with relation to the invention described herein is that they sometimes fog up or cloud up due to atmospheric conditions. When this occurs and the hunter, for example, observes a sudden target, he is prevented from using the telescopic sight due to the aforementioned problem and is prevented from using the conventional open sight because the telescopic sight is mounted so as to obstruct the conventional sights. The present invention is directed to overcoming this problem.

Specifically, it has been discovered that by providing auxiliary open front and rear sighting assemblies that the same can be placed on the tubular part of the telescopic sight so that in the instance described above, the hunter, for instance, need merely raise his eyes slightly and sight through the open sights thus provided which can be done rapidly and with minimum difficulty.

It has further been found that by providing a horizonta or transverse adjustment for the sighting element of the front sight and a vertical adjustment for the sighting element of the rear sight that these sights can be registered or zeroed prior to beginning use of the weapon thereby insuring accuracy when and if the auxiliary sight is employed.

Accordingly then, production of an improved auxiliary open sight of the character described becomes the principal object of this invention with other objects thereof becoming more apparent upon a reading of the following ICC brief specification considered and interpreted in light of the accompanying drawings.

On the drawings:

FIG. l is a side elevational view showing the improved auxiliary sight mounted on a conventional telescopic sight.

FIG. 2 is a view taken `along the lines 2-2 of FIG. 1 partially broken away and showing the rear sight assembly.

FIG. 3 is a side elevatio-n of one of the brackets of the rear sight assembly partially in section.

FIG. 4 is a lview taken along the lines 4-4 of FIG. 1 and partially broken away showing the front sighting assembly.

FIG. 5 is a side elevation of the front sighting assembly.

FIG. 6 is a side elevation of a modified form of the rear sight.

Turning rst then to FIG. 1, it will be noted that, in general, the invention disclosed herein includes a front sighting assembly 20 and a rear sighting asembly 30 mounted on a conventional telescopic sight 10.

The telescopic sight 10 will not be described in any great detail since it is conventional in nature except to point out that it has a rear or occular end 11, a front or objective end 12 and is mounted on the barrel of a ritie or shot gun (not shown) by means of brackets 13 and 14. The ends 11 and 12 are inetrconnected by tubular body 15 and all of this construction is conventional.

Turning next then to FIG. 4 for a detailed description of the front sighting assembly 20, it will be seen that the same includes a pair of opposed brackets 21 and 22 each of which has a top and bottom strap joined together by a convex central portion. These brackets both have complemental through apertures in the bottom strap 21a, 22a and in the top strap 2lb, 22b. In this fashion the same can be joined together by means of the nut and bolt 23a and 23b, for example, or with a nut and stud such as indicated at 24a and 24h. FIG. 4 clearly shows the manner of joining these brackets together so as to form a through central area in the neighborhood of the convex central portions with this area intending to encircle the tube 15 of the scope 10 as is clearly shown in FIG. 1.

Each of the brackets 21 and 22 also has a recessed area 21C and 22C adjacent their tops and when the brackets have been joined together as is shown in FIG. 4, these recessed areas combine to form a pocket to receive the sight itself as will now be described.

The bracket 22 has a through bore 22d opening into the` pocket just described with a counter bore or enlarged area 22e being disposed on the inside of the pocket.

The front sighting assembly 20 also includes a sight 27 which is an elongate conventional sighting element except that it has a through threaded bore 27a therein. The assembly is also provided with a screw 25 having a threaded shank 25a and a head 25b and this screw is of suicient size to pass through the bore 22d and threadingly engage the sight 27. In this fashion adjustment of the screw 25 by turning the head 25b will move the sight 27 to the left or t0 the right of FIG. 4 depending upon the direction the screw is rotated.

Also included in the front sighting assembly 20 is a spring 26 surrounding the shank 25a of the screw 25 and having one end seated in the counter bore 22e and the other end bearing against the sight 27 so asto maintain proper tension on the sight at all times.

Furthermorethe head 25b has a serrated edge 25e` which coacts with a complementally serrated projection 22jc on the outside of the bracket 22 and in this fashion, the screw will tend to be held rmly in place against inadvertent rotation.

Turning next then to FIGS. 2 and 3 for a more detailed description of the rear sighting assembly 30, it will be seen that this assembly also includes complemental brackets 31 and 32 including top and bottom straps interconnected by convex central portions and which have through apertures 31a, 32a, 31b, and 32b similar to the previously described front sighting assembly. The brackets 31 and 32 can be joined together by the nut and bolt 33a and 33h or the studs and nuts 34a and 34b in the same fashion as earlier described with regard to the front sighting assembly 20.

Again, once these have been joined together about the tube of the telescopic sight 10, the screws can be tightened and the rear assembly can be firmly held in place.

The rear assembly 30 also employs cut out areas 31C and 32C in the tops of the respective brackets so that a pocket is formed once the brackets have been assembled.

The rear sight 37 having a generally L-shaped cross sectional configuration with a vertical leg 37a and a horizontal base 37b lits into the pocket just described. This sight also has a through threaded bore in its base at as 37e.

Each bracket 31 and 32 of rear sighting assembly 30 has a complemental arcuate groove which extends from the top of the bracket to the pocket and when the brackets are joined together, these grooves cooperate to, in effect, form a through bore.

The rear assembly also includes a screw 35 having a threaded shank 35a and a head 35b. The shank of the screw 35 will pass through the bore formed by the grooves in the brackets and threadingly engage the bore 37C of the rear sight. Thus rotation of the screw will serve to move the rear sight 37 vertically.

For purposes of maintaining tension on the rear sight, a spring 36 ts around the shank of the screw 35 with one end seating against the top of the cut out areas 31C, 32e and the other end seating against the base of the sight 37.

Furthermore, the head 35b has a series of serrations 35e` which coact with a series of serrations on the projecting portion 31j of the brackets to again prevent inadvertent rotation of the screw.

In use or operation of the improved auxiliary sight, it will rst be assumed that the scope has been mounted on the barrel of the ritle or shot gun as the case may be.

At this time it is merely necessary to install the front and rear sighting assemblies and 30 by clamping the brackets together about the tube 15 of the telescopic sight 10 as full described above. It is then a simple matter to sight in the front and rear sights by adjusting the same as required by means of the screws and 35.

Once this has been accomplished, the user has the option of either employing the telescopic sight or employing the open sight. It should be noted that neither of these sights interfere with the operation of the other.

In the normal instance, the brackets will be of such dimension that the interior diameter of the opening formed by the convex central portions thereof will approximate the outer diameter of the tube 15 of the telescopic sight. These sights come in standard sizes and it is contemplated that the auxiliary sights would be in complementally standard sizes.

Optionally, a somewhat improved performance may be obtained by utilizing gaskets or bushings 40 and 41 inside the brackets and around the periphery of the tube 15. The principal advantage to be gained here is to avoid marring or scratching of the outer surface of the telescopic sight.

FIG. 6 shows a modied form of the rear sight 27 having improved adjustment features. In this regard, the bell of the regular telescopic sights may vary in size. If the bell is particularly large it may be desirable to elevate or adjust rear sight 27 to clear the bell. Therefore, the sight 27 may be provided with a plurality of threaded bores 27a, 27a which can be selectively engaged with screw 25 to permit the required vertical adjustment.

It has been shown, therefore, how 4by provision of a relatively simple front and rear sighting assembly that the advantages of both an open and a telescopic sight can be simultaneously achieved without impairing the operation or function of either.

While a full and complete description of the invention has been set forth in accordance with the dictates of the patent statutes, it should be understood that modications can be resorted to and that the invention is not intended to be limited to any particular size, dimension or to any particular material.
